Abstract

The permanent magnet eddy-current coupler (PMEC) is a kind of non-contact, stepless speed regulation device and has been widely used in transmissions. However, the current PMECs are coaxial and cannot achieve transmission and speed regulation in intersecting axes. An intersecting-axis permanent magnet (PM) eddy current coupler (IPMEC), which consists of a disk-type PM rotor and a barrel-type conductive sheet (CS) rotor arranged with intersecting axes, is proposed. It generates eddy currents through the speed difference between the two rotors and uses the non-contact electromagnetic force between the eddy currents and permanent magnets to transmit torque. During operation, the speed can be adjusted by altering the coupling area or air gap. A theoretical model of the IPMEC based on the equivalent magnetic circuit method is presented and verified by finite element simulation using ANSYS. Then, the effects of the pole number of the PMs, the radius of the CS rotor and the PM rotor on the performance were analysed, and the design method of the IPMEC was proposed. This study can be used to expand the application range of PMECs.

相交轴永磁涡流耦合器的建模和分析

永磁涡流耦合器（PMEC）是一种非接触式无级调速装置，已广泛应用于传动领域。然而，目前的永磁涡流耦合器都是同轴的，无法实现相交轴的传动和调速。本文提出了一种相交轴永磁涡流耦合器（IPMEC），它由盘式永磁转子和筒式导电片（CS）转子组成，两者轴线相交。它通过两个转子之间的速度差产生涡流，并利用涡流和永磁体之间的非接触电磁力来传递扭矩。在运行过程中，可通过改变耦合面积或气隙来调节速度。本文提出了基于等效磁路法的 IPMEC 理论模型，并使用 ANSYS 进行了有限元仿真验证。然后，分析了永磁体极数、CS 转子和永磁转子半径对性能的影响，并提出了 IPMEC 的设计方法。这项研究可用于扩大 PMEC 的应用范围。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
